A quick scan of the code would suggest you're hitting this error: https://github.com/dhowden/tag/blob/e80a3fa76a9645b4a90127deab5b271d8c5bcf85/id3v2frames.go#L505

Can you post the first few hundred bytes of one of the files that is failing? (maybe share publically using Dropbox or similar).

I ran into the same issue with a few songs. Here's the first 200 bytes from one. Let me know if more would be helpful.

$ cat print_bytes.py
file = open("01 These Days.mp3", "rb")
bytes = file.read(200)
file.close()

hexchars = []
for b in bytes:
  hexchars.append(b.encode("hex"))
print " ".join(hexchars)

$ python print_bytes.py

fwiw this is an old song that I appear to have downloaded from https://www.jamendo.com/album/30315/only-the-missile in ~2013. I just downloaded it from there again and here are the new leading 200 bytes. This one's tags don't have issues.
